"Energy Source largest in the world, the source of life of every plant and animal, but still the source used so little? Today is the sun. This energy can be converted into a driving force, dynamic and electric, and even after exhausting all uranium and thorium from? Earth Energy sun will

continue to flow to us almost without limit "? David Ben-Gurion in 1956

Picture: Dr. Zvi Tabor and Prime Minister David Ben-Gurion imply the panel's first solar developed Tabor International Laboratory for Physics in 1955. Israel has played a historical role in pioneering research and development of renewable energy and the panel of Tabor became a

vital technology for solar power stations around the world.1956


Infrastructure Ministry's policy is to integrate renewable energy electricity

generation systems in Israel The purpose of the firm's policy is vigorous development and

integration of renewable energies in the energy market of Israel in order to advance the country toward energy independence and security and to strengthen integration in environmentally sensitive culture. These objectives will be achieved by leveraging advancements in industry and technology development in parallel Israeli and livelihoods, especially in the periphery 1.

The policy is designed to optimally implement Government Resolution 4450) SE / 176 (regarding the production of electricity from renewable energy sources.

"2020 may reach 8% renewable energy”

Ministry of National Infrastructures policy guidelines in renewable energy

• Creating certainty in renewable energy electricity generation in clarifying the goals by 2020.

• Encouraging the construction of electric power plants using renewable energy in Israel in general and in particular the outlying areas.

• Increasing the energy security of the State of Israel.

• Encouraging electricity generation technologies "friendly" environment.

• Increasing electricity generation from renewable energy sources while reducing the cost burden for consumers.


The heart of the development of photovoltaic private industry market in Israel and its neighbors will be

reflected in the way we produce, distribute and consume energy

Renewable energy sources in 2012 accounted for only 5% of primary energy consumption in Israel, where the main energy source is utilized mainly solar water heaters.

For power generation renewable energy contributing only about half a percent, which is the lowest rate in the world. In contrast, the supply of solar heating contributes approximately 39%, which is the highest rate in the world. As of 2012, still about 95% - Israel's primary energy supply comes largely imported fossil fuels.The market PV world grew by more than 40% a year in recent years and turns valuable contribution for electricity generation.

Energy PV is important because of the nature decentralized / centralized, flexible use of the urban environment and there is a huge potential to lower costs.

Industrial photovoltaic exploiting the potential of a more and more in recent years, with the most downloaded installation prices in half in recent years.

Existing developments focused on improving existing modules and system components by improving energy efficiency and reduced use of materials.

=Direct electrical conversion


An advanced system for hybrid solar (PV-T)) produces simultaneously

electricity (photovoltaic) and hot water (solar thermal) for homes and buildings combines photovoltaic panel with a heat exchanger on the bottom board, to produce 2 to 4 times more energy than photovoltaic traditionally panel. The solution is ideal for new regulations for energy efficiency and is designed to make homes and buildings to power stations Mini positive energy..

1. Innovative heat exchanger: completely integrated into the board, allowing excellent heat transfer between the photovoltaic panel front and the water flow.

2. Super slim design: standard dimensions of the photovoltaic panel (cell 6 inches, 60 cells).

3. High-performance photovoltaic cells volts: mono-crystalline, high efficiency, cooled by water flow.

Hybrid system


2 in 1 integrated system to produce electricity + hot water

The hybrid system provides hot water and electricity, and is a nice solution for private homes, new construction, government offices, schools, new PV installations, or to existing PV.

The solar panels capture the wasted heat of the solar panels and turn up the heat in their water and electricity for a private home.

This hybrid solution provides incredible 60-70% of solar energy compared to 15-20% with a PV system, which means watt manufacturing cost is cut in half as a result of "heat extraction“ of the PV cells and converting them into electricity.

Solar systems hidden under the PV panels and requires no additional roof space, as opposed to separate solar thermal systems.


Volther Hybrid PV- T Panels

PARADOX & PROBLEMPhotovoltaics (PV) are semi conductors and operate in a paradox. They need sunlight to generate electricity but suffer a degradation in performance as they get hotter.


A typical PV Efficiency

A typical PV panel on a bright sunny day will reach temperatures in excess of 110°C. This can reduce efficiency by as much as 43% on a hot day or 0.5% for every 1°C temperature rise. Standard PV Panels typically only convert 10-15% of solar radiation into electricity and the rest is dissipated as waste heat.

For Pitched Roofs

Pitched roof mounting kits are designed with ease of installation and aesthetics in mind.We developed mounting systems with hanger bolts and roof brackets as well as accessories for all roof types.


For Flat Roofs

Using the Premium Flat roof mounting system, PV-T panels can be installed on flat roofs of every type. Together with the module frames, the rear supports of the mounting elements form a static unit capable of bearing particularly heavy loads. It is possible to make installation horizontally or vertically


For Roofs Integration

Roof integrated mounting option allows highest- flexibility to choose between landscape and portrait orientation and to arrange the respective PV-T modules according to your own preferences. The advantages of this method of installation include perfect integration of panels so they lie particularly flat on the roof, and the very slender appearance of the system.While aesthetic considerations take precedence, the performance of the cells will never be a problem.


System Components

Typical system components are listed below. Actual configuration will vary according to each application: PV-T PanelsInverterControl System & SensorsPump StationHeat ExchangerHot Water Storage TankMounting kitCables and Pipes


Optional System Components

The PV-T panels can be used in conjunction with other technologies to further enhance energy efficiency if desired. Examples are: Geothermal Heat Storage: Excess heat produced by the PV-T panels can be stored in the ground for use at a later time => summer heat can be used into the winter to maximize energy use. Battery Storage System: Can be used to create an off-grid system => excess electricity generated during daytime can be stored and used at night. Fuel Cell Storage: Excess electricity from daytime can be used to generate hydrogen for use in a fuel cell system at night.

Great setup of the hybrid system to generate electricity on the roof of the Federal Building in

BostonBoston, MA – The U.S. General Services Administration has committed itself to

sustainability at an Earth Day event held today at the Thomas P. O’Neill, Jr. Federal Building.

This solar energy system is designed to produce electricity and hot water through the use of an innovative photovoltaic-thermal hybrid technology that combines a solar panel and thermal collector into a single module. The installed array of hybrid modules will produce approximately 30,000 watts of electricity and 69,000 watts of thermal energy to heat water. The reduction in greenhouse gas emissions associated with this project is estimated to be approximately 64,904 pounds of carbon dioxide, equivalent to the work of 4,993 mature trees. The system is the largest rooftop hybrid solar installation in the U.S and is also the first installation of photovoltaic-thermal hybrid solar technology on a federal or commercial building.

Is one day we dare to look in the eyes of our children and to admit that we had the chance but we did not have the courage ? We had the technology, but we did not have a

vision?
